Lethal Service Control Valve Solutions

There are numerous toxic and lethal fluids where even minimal exposure can cause an immediate and severe danger to human life, such as those in chlorine service and ammonia service. Based on the process fluid, government regulations, and customer specifications, control valve bellows might be required to ensure zero leakage. Emerson's Fisher™ control valves can be equipped with Fisher™ ENVIRO-SEAL™ bellows seal bonnets, which enhance sealing capabilities and ensure longevity, particularly in applications where emissions from a valve stem to the atmosphere cannot be tolerated.
